Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of resin high temperature foamed gas flow regulator, including: guide pillar 1, foaming gas
Body flow controlling unit 2；Foamed gas flow controlling unit 2 includes four-bladed vane 3, compression spring 4, clamp nut 5, impedance screw
6 and spherical plug 7；Four ends of four-bladed vane 3 are respectively fitted on four guide pillars 1, and clamp nut 5 is arranged on guide pillar 1 one end, pressure
Being provided with compression spring 4 between jack panel 5 and four-bladed vane 3, guide pillar 1 other end is fixed on cover plate 9；Spherical plug 7 is along axis
It is cylindrical for having through hole, spherical plug 7 one end, is connected with the spherical structure of the other end, is arranged on ten by cylindrical one end
At letter stencil 3 bottom centre；Vent connection 8 is arranged on cover plate 9, and vent connection 8 has through hole, through hole one end to be cone along axis
Being internally formed internal conical surface at vent connection 8, internal conical surface is directed at one end that spherical plug 7 is spherical；Solar term screw 6 is from four-bladed vane
3 centers penetrate, and one end is stuck in four-bladed vane 3 top, and the other end passes the through hole of spherical plug 7 and penetrates the logical of vent connection 8
In hole.The material selection 65Si2Mn of compression spring 4, remaining parts material selection rustless steel 1Cr18Ni9Ti.
For the requirement of the foaming that reaches a high temperature, the resin high temperature foamed gas flow regulator band that this utility model makes
Having foamed gas flow controlling unit 2, it is applied in combination with the guide pillar 1 on cover plate 9 and vent connection 8, can reed time controll foaming
Time the spill-out of resin liquid and mould in blow pressure；Spherical plug 7 and impedance screw 6 are threaded connection and four-bladed vane group
It is combined.
The resin high temperature foamed gas flow regulator that this utility model makes is arranged on for making phenol formaldehyde foam
On mould, before baking oven put into by the mould equipped with expandable resin liquid, by clamp nut 5, compression spring 4 is applied pretightning force,
Spherical plug 7 is made to be tightly pressed against on the internal conical surface of vent connection, after mould enters baking oven, along with temperature raises, foaming mould
The gas pressure of interior resin expanded formation gradually rises, and pressure acts on impedance screw 6 and spherical plug 7, four compressions
The pretightning force that spring 4 applies forms one with the gas pressure of the resin expanded formation acted on impedance screw 6 and spherical plug 7
Individual dynamic balance state, the impedance screw 6 in foamed gas flow controlling unit 2 can play and slow down the effect that resin liquid is overflowed.
This utility model description is unspecified partly belongs to general knowledge as well known to those skilled in the art.
